Lesser calamint is a perennial shrub, forming a compact mound of shiny, green oregano-like leaves. The flowers are lavender pink or sometimes blue flowers. The lesser calamint smells like a cross between mint and oregano. It attracts honeybees and butterflies. Lesser calamint usually grows in the summer, and well into the fall. It can become dormant in the winter months. Lesser calamint or Calamintha nepeta often grows wild, but can also be kept in pots.
